With a Rinnai tankless water heater, you can shower, wash clothes, and run the dishwasher—all at once—without worrying about depleting a storage tank. Hot water is produced on demand, giving you the freedom to use multiple fixtures without scheduling around the water heater.

Warranty

Rinnai offers generous warranty terms that reflect the brand’s commitment to durability and reliability.

Warranty

Rinnai backs its tankless water heaters with some of the strongest warranties in the industry—often up to twice as long as standard tank models. This coverage reflects their commitment to long-term reliability and product excellence. Many models include extended protection for both heat exchangers and parts, ensuring that you’re safeguarded against unexpected repair costs. It’s more than a warranty—it’s a promise that your hot water system will perform dependably for years to come.

Easy Wi-Fi Accessible

With Wi-Fi capability, you can adjust settings and run diagnostics right from your smartphone.

Easy Wi-Fi Accessible

Rinnai’s Wi-Fi–enabled models put you in control of your hot water system from anywhere. Through the mobile app, you can adjust temperature settings, activate recirculation, monitor performance, and even run diagnostic checks—all from your smartphone or tablet. The system can send alerts for maintenance reminders or issues, helping you stay ahead of potential problems. Paired with smart home assistants, it also offers hands-free voice control, making hot water management seamless and effortless.

Space-Saving Design

Compact, wall-mounted units free up valuable home space and greatly reduce leak risks.

Space-Saving Design

About the size of a carry-on suitcase, a Rinnai tankless water heater mounts neatly on a wall, opening up valuable floor space. Unlike bulky tanks, there’s no large reservoir to store or maintain—and many parts can be replaced individually, reducing waste and keeping the system running for years.
